## Dimensioning Angle

Dimension Angle dialog box

The Insert | Dimension | Angle menu option calculates the angle between a selected feature and either a second selected feature or a coordinate axis.

The measured value is an angle (blue). The Angle tolerance band is another angle (black).

For a 2D angle type, Planner projects the vectors onto the current workplane, and it calculates the angle from the first feature to the second feature or axis.

Planner gives a positive angle if it calculates the angle in a counter clock-wise direction. It gives a negative angle if it calculates the angle in a clock-wise direction.

The To and From options determine the direction of the calculation and the resulting sign (positive or negative):

- If you select To, Planner calculates the angle from feature 1 to feature 2 (or selected axis).

- If you select From, Planner calculates the angle to feature 1 from feature 2 (or selected axis).

By default, Planner uses the angle from feature 1 to feature 2 (or the selected axis). If you want the supplemental angle (180 degrees - angle), mark the Supplemental Angle box.

Consider the following examples:

Example A - From line feature (Line 1) to the Y axis (To option)

Example B - To line feature (Line 1) from the Y axis (From option)

Example C - From line feature (Line 1) to the Y axis (To option with Supplemental Angle)

Example D - To line feature (Line 1) from the Y axis (From option with Supplemental Angle)

If you select one of these features (or feature types), Planner rotates the surface normal vector 90 degrees clockwise to represent a vector along the surface:

- Plane

- 2D feature with width

- 3D feature with width

Consider the following examples:

Example E - From plane feature with normal vector (Plane 1) to line feature (Line 1) (To option)

Example F - To plane feature with normal vector (Plane 1) from line feature (Line 1) (From option)

Example G - From plane feature with normal vector (Plane 1) to line feature (Line 1) (To option with Supplemental Angle)

Example H - To plane feature with normal vector (Plane 1) from line feature (Line 1) (From option with Supplemental Angle)
